Hi, Via the wonder that is eBay, I have procured an AMD Duron Mobile 1000 (supposedly).I was taking the cheap route to slightly upgrade another desktop PC, and this was the fastest processor that it's motherboard would take.I installed it and BIOS informed me that it was only a 500 Mhz CPU, which was concurred by Windows.

Is this some kind of power thing different from a laptop to a desktop causing it to run at half speed, or have I just been done?The serial on the processor is 27067, and the other number is DHM1000AVS1B.

It is working fine, you have to understand how the mobile cpu works, more than likely it has booted in a "SAFE" mode. The board will boot it with the lowest possible multiplier for that cpu ~5 and use the 100MHz bus = 500MHz Duron.

What you need is some software that will change the multiplier via the windows environment.
